The paper settles a discrepancy between two smart-metering methods. The issue bears on a billion installed smart meters and $36B electric-energy trading market. The contemporary problem of the energy-metering registration gap between the methods, relates to energy-trading unified-billing, and it will aggravate in the future. A mathematical definition for active and reactive, import/export energy-metering formulas is given for vector/arithmetic common metering models employing energy formulas rather than power, energy being the language of smart metering design/usage/billing. Economic reasoning, difficulty of implementation, and required regulator's flexibility at establishing different import/export tariffs-per different tariff program-types are explained. Innovations in the presented work include: (1) mathematical formulation of metering-methods-definitions that is validated over: one EU organization, twelve major meter manufacturers, twenty model-types, is presented and tested. (2) formulation of drivers for 100% accurate conversion from one method to another is developed. (3) fifteen real-life experiments covering the entire problem spectrum are conducted with new results, discovering new energy/tariff "conservation-rules", relevant to manufacturers/utility companies/regulators/customers. (4) a correct segmentation of customers to energy/tariff registration-gap is generated. (5) an algebra that is suitable to energy metering/conversion/tariff computation-and-design is presented. (6) research reduces the cost of a contemporary solution by 98%. (6) Advantages/disadvantages of each method are named. (7) scenarios where one of the energy methods may be incorrect are considered-and-rejected. Eleven theorems formulated and proved, and fifteen field test cases covering the entire electricity market. (8) regulators may maintain arithmetic meters, enjoying their added value, and manage precise arithmetic/vector metering using these meters- especially using load profile and potentially satisfying with billing registers.

There exist several interconnected issues that hinder the development of family medicine in Commonwealth realms such as the United Kingdom, Canada, New Zealand, and Australia. These issues affect both the medical and nursing professions. Family physicians, in most countries including the United Kingdom, are not considered "specialists" and are called "general practitioners" instead.

From August 2021 to December 2023, one adult male Mediterranean monk seal was repeatedly registered, through a systematic monitoring camera system, frequenting a marine cave in southern Kefalonia Island, central Ionian Sea, Greece. The presence of the same adult seal in a series of caves and overhangs in a bay in northwestern Zakynthos, southern Ionian Sea, in September 2023 and May 2024 was verified through opportunistic surveys and citizen science. The two locations are ca.

While peatland C cycling is generally well covered, understanding of the role of soil fertility in driving the spatial variation of C fluxes within peatlands remains scattered. Our aim was to examine the relative effects of fertility and microtopography on CO and CH exchange within a boreal fen and to link these effects to the spatial variation in plant and soil attributes. Fertility zones (eutrophic, mesotrophic, oligotrophic) were judged by moss species appearances, and the growing season CO and CH exchange was measured by static chambers for microforms (string, Sphagnum lawn, flark) and fertility zones and by eddy covariance technique for the entire ecosystem in three years.

Background: Frequent attenders (more than 11 annual contacts) use more resources than most other patients in general practice.
Aim: We aim to study what characterises frequent attenders related to age, gender, mode of contact (face-to-face, email, phone), and patient contact (GP or GP staff).
Design & Setting: We use patient data from 11 Danish GP clinics and 38.
